Instruction Manual
6.4.7. Maintenance Mode
- It is a mode that displays value converted from processor after inputting 20mA current to (mA)
-
terminal.
- Press "FUNC" S/W when the displayed number is stable to display SUC (Success) for a current
-
input within normal range and move to the next item.
- C-F (Calibration-Fail) displays when a current out of range is inputted. After confirming input
-
current after re-display of current value then press "FUNC" S/W again to confirm.
- When "RESET" S/W is pressed, it returns to gas concentration display mode.
- When "oUt" is selected, it is a mode after input current, which sets 4mA output current.
-
(Default 4.00)
- Connect ammeter to 4~20 mA output terminal and press "UP" S/W or "DOWN" S/W to match the
-
values on ammeter and FND then press "FUNC" S/W to set output current and move to the next item.
- When "RESET" S/W is pressed, it returns to gas concentration display mode
- Mode that sets 20 mA output current. (Default 20.00)
- Due to display limit of FND, 10-digit and decimal point digit flashes in 0.5 sec interval.
- Connect ammeter to 4~20 mA output terminal and press "UP" S/W or "DOWN" S/W to match the
-
values on ammeter and FND then press "FUNC" S/W to set output current and move to the next item.
- When "RESET" S/W is pressed, it returns to gas concentration display mode

■ Pressing both "RESET" and "TEST" S/W for 2 sec or longer in gas concentration display mode enters
Maintenance mode.
■ "RESET" S/W must be pressed in Maintenance mode to return to gas concentration display mode.
- Mode that selects function to set current input and output values that are reference of Channel
-
unit. Pressing "UP" S/W or "DOWN" S/W displays "In" or "oUt", respectively.
- When a desired mode is displayed, press "FUNC" S/W to set it and enter the mode.
- When "In" is selected, mode sets current input. When "oUt" is selected, mode sets current
-
output.
- When "RESET" S/W is pressed, it returns to gas concentration display mode.
- It is when "In" is selected and a mode that sets by inputting 4 mA current.
- Press "FUNC" S/W to enter function that displays current input by number.
- When "RESET" S/W is pressed, it returns to gas concentration display mode.
